You are traveling on an elevator. The net force (Fn) of the elevator is pointed in the upward direction. In this instance, can the elevator be moving downward? What would the elevator be doing in this situation? Please explain
Given: The net force (Fn) of the elevator is pointed in the upward direction.
In this instance, can the elevator be moving downward? Yes.
And, if the net force on the elevator is in upward direction and the elevator is moving downward- then the elevator must be deccelating (slowing down). Because in this case, net force is opposite to the direction of motion.

You are in your favorite elevator, coming to a stop as you go from the ground floor to the 4th floor. a) What forces are acting on you as you are coming to a stop in the elevator? Normal force upward and Force of gravity upward Normal force downward and Force of gravity upward Normal force downward and Force of gravity downward Normal force upward and Force of gravity downward Just the Force of gravity downward b) As you are...
A simple elevator ride can teach you quite a bit about the normal force as this rider below can (hopefully) tell you. There are three different scenarios given, detailing the rider\'s experience in an unnamed hotel. For each scenario, calculate the normal force, FN,1-3, acting on the rider if his mass is m = 76.6 kg and the acceleration due to gravity g = 9.81 m/s2. In scenario 1, the elevator has constant velocity. In scenario 2 the elevator is moving...
E. Suppose you are standing on the scale in the elevator and the elevator is accelerating downward with an acceleration smaller than 9.8 m/s2 i. Draw free-body diagrams of yourself, the scale, and the floor of the elevator where it interacts with the scale. ii. How must the magnitude of the force exerted by the scale on you compare with your own weight? iii. How must the reading on the scale compare with the reading you make when the elevator...
An elevator is being lifted up an elevator shaft at a constant speed by a steel cable as shown in the figure. Assume that all frictional forces can be ignored. In this situation, forces on the elevator are such that: steel cable elevator going up at constant speed o the upward force by the cable is greater than the downward force of gravity. the upward force by the cable is equal to the downward force of gravity. the upward force...
Question 5 (3 points) An elevator moves downward while slowing down. What is the direction of the net force that acts on the elevator? The net force points upward. The direction of net force cannot be determined. The net force points downward. The net force is zero and has no direction.
An elevator is pulled upward so it moves with increasing upward speed?the force exerted by the cable on the elevator is constant and greater than the downward gravitational force exerted by Earth. When the elevator is moving up medium-fast, the force exerted by the cable on the elevator changes abruptly to just balance the downward gravitational force of Earth?the sum of the forces that the cable and Earth exert on the elevator is now zero.
The upward normal force exerted by the floor is 620 N on an elevator passenger who weighs 650 N. What is the magnitude of the acceleration? What is the direction of the acceleration? (upward or downward)
a 3000 N upward tension force is exerted on a 320-kg downward-moving freight elevator. Determine the acceleration of the elevator.
(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? T w Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? T w Both forces are equal. (c) When the elevator is moving upward, but the acceleration...
An elevator starts from rest at the bottom of a building and is now moving steadily upward (no longer speeding up). Which statement is correct about its motion now and why? A) The net force on the elevator is zero B) The net force on the elevator is greater than zero C) The net force on the elevator is negative, downward D) The net force is equal to the weight of the elevator
